Abstract

PURPOSE:To obtan the speaker with high efficiency and performance in simple construction, by providing the primary coil for signal so that the diaphragm plate driving coil can be the secondary coil. CONSTITUTION:The magnetic circuit consisting of a magnet f2 and plate e2 is the same as conventional speaker magnetic circuits. The voice coil a2 is constituted with cylindrical conductors and it acts like the secondary coil of one winding. Under the center pole, the primary coil g2 to which the drive signal d2 is fed, is provided. The voice coil a2 is driven with the secondary electromotive force of the signal current fed to the primary winding g2.
